Let w be the width. Length is 6w
Perimeter is 70 m
so w + w + 6w + 6w = 70
w = 70/14 = 5, l = 30m.
Area = l * w = 30 * 5 = 150
Answer:
A = 150 feet
Step-by-step explanation:
perimeter of rectangle = 2w + 2l
l = 6w
70 = 2w + 2(6w)
70 = 2w + 12w
70 = 14w
w = 70/14
w = 5
l = 6 x 5 = 30
area = l x w
A= 30 x 5 = 150 feet
don't forget the units
